I found these 5V chargers at Dollar Tree to work for me when powering an Wemos ESP82166.<\/p>\n

\"\"<\/a>\u00a0Pretty easy to find and cheap.<\/p>\n

\"\"<\/a>\u00a0Start with the USB part and remove that one screw.<\/p>\n

\"\"<\/a>\u00a0Should be come apart pretty easily.<\/p>\n

\"\"<\/a>\u00a0On the 12V side firmly grip the cone and rotate it off.<\/p>\n

A bunch of pieces should come out. \u00a0They are not needed.<\/p>\n

Here are the where the 12v inputs and ground should go. \u00a0The solder comes off surprisingly easily.<\/p>\n

\"\"<\/a><\/p>\n

Here are the 12V leads soldered on.<\/p>\n

\"\"<\/a><\/p>\n

Electrical or duct tape should hold the ground lead securely.<\/p>\n

Seems like a lot of work, but it is cheap and small 5V source for a wemos that itself has a built in regulator.<\/p>\n
